How Much Does It Cost to Run a Smart Speaker in the US? (2026)
Smart speakers listen constantly and draw 2 to 4 watts idle, rising slightly when playing music. Each one adds around 20 to 30 kWh a year, which matters mainly if you have many.
A typical smart speaker (3 W) costs $0.001 per hour, or about $0.39 per month at 24 hours a day in United States (average). Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (2 W) | $0.000 | $0.009 | $0.26 | $3.15 |
| Typical (3 W) | $0.001 | $0.013 | $0.39 | $4.73 |
| High (6 W) | $0.001 | $0.026 | $0.78 | $9.46 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 26 kWh per year.
In the US, with electricity at $0.18 per kWh (source: EIA Electric Power Monthly, 2026-06), a typical smart speaker costs $0.001 per hour and about $4.73 per year at 24 hours a day. Each $1.00 of electricity buys roughly 1,851.9 hours of use.
How to lower the cost of running a smart speaker
- Count them. Six speakers at 3 watts each cost more than a fridge over a year.
- Turn off the always-on display on models that have one.
- Unplug speakers in rooms you rarely use.
In standby it draws about 2 W, which adds roughly 18 kWh ($3.15) per year if it is never unplugged.
Frequently asked questions
How much electricity does a smart speaker use?
About 25 kWh a year at 3 watts continuous.
